ABOUT SORIATANE
Soriatane is a convenient, once-daily oral medication supplied as 10 mg and 25
mg capsules that is indicated for the treatment of severe psoriasis in adults,
including plaque, erythrodermic, pustular, guttate and palmar-plantar. Clinical
efficacy studies show that 76% of patients taking Soriatane have statistically
significant improvement in as little as 8 weeks. At six months, 40% of patients
experienced complete or almost complete clearing of their psoriasis; at 12
months, patients continued to experience statistically significant improvement
in symptoms. Since Soriatane is neither immunosuppressive nor cytotoxic, it can
be used without the risk of reducing a patient's resistance to common
infections.

In women of childbearing potential, Soriatane should be reserved for patients
who have not responded to other therapies or whose clinical condition makes
other treatments inappropriate, because the drug may


                                     -More-


cause serious birth defects. Women who are pregnant or might become pregnant
within three years after stopping therapy should not take Soriatane.

Aside from birth defects, less frequent but potentially serious adverse events
that have been reported include liver toxicity, pancreatitis and increased
intracranial pressure, as well as bone spurs, alteration in lipid levels,
possible cardiovascular effects and eye problems. For more information about
